2-9 Claims. (01. 51135) This invention relates to finishing machines andis herein illustrated as embodied in a heelbreast-scouring machine ofthe type utilizing a driven scouring belt which passes over a fixture 51adapted to support the belt against the pressure of the work. In variousof its aspects, however, the invention is not limited to machinesprovided with a finishing tool of the type above referred to.

One object of this invention is to provide a finishing machine havingimproved means for controlling the presentation of a work piece to afinishing tool. As herein illustrated and in accordance with a featureof the invention, a finish- 157 ing tool and a gage member are mountedfor relative movement from an inoperative position wherein the gageholds the work piece out of con tact with the finishing tool during thepresentation of the work piece to the gage member, to go; an operativeposition wherein the work piece is in engagement with the finishingtool. An advantage of this arrangement resides in the fact that the workpiece can be presented to the gage member while the gage member andthefinishing tool 25. are in the inoperative position, thereby avoidingany finishing action upon the work piece during the preliminarypositioningthereof relatively to the gage member and until the workpiece has been properly positioned by the gage member with respect tothe finishing tool. In the illustrated machine the gage is constructedand arranged for engagement with the breast surface of a heel toposition the heel-breast surface in face-to-face relation to theoperative surface of the finishing 315i tool, and a yieldable support isprovided for the gage to enable the gage to move relatively to thefinishing tool while maintaining the orientation of the gage and therebyof the heel as the heel-breast surface is moved against the operam tivesurface of the finishing tool. A stop may conveniently be provided fordetermining the operative position of the gage with respect to thefinishing tool. As illustrated, both the finishing tool andthe gage havetheir working surfaces curved to a form substantially complemental tothat of the heel-breast to be treated. The finishing tool of theillustrated machine consists of a scouring belt supported against thepressure of the work by a form block shaped to impart the desired convexcurvature to the scouring belt.

In accordance with another feature of the invention, a second gage,which extends transversely of the heel, is provided for substantiallyline contact with the tread surface of the heel to prevent transversetilting of the heel while permitting the inclination of the heel to bevaried in a direction which is heightwise and lengthwise of the heel.This second gage serves also to determine the heightwiseextent of theheel-breast surface to be presented to the finishing tool. A third gagemay also be provided, as in the illustrated machine, for engaging thetread surface of the forepart of the shoe to insure accuracy in theangle of presentation of the heel-breast surface to the finishing tool.

l'he invention further consists in various features of construction andcombinations of parts herein disclosed and claimed, the advantages ofwhich will be apparent-to those skilled in the art from the foregoingdescription, reference being had to the accompanying drawings, in whichFig. lis a side elevation of the machine embodying the invention;

Fig. 5 is a perspective view showing an alternative form oftheheel-positioning member.

The supporting structure of the machine consists of a standardlflcarrying at its upper end a hollow frame member 12 which supports theoperative instrumentalities of the machine. Hinged cover plates Hand 16provide access to the interior of the frame 12 at each end thereofrespectively. The frame l2 houses an abrading belt 18 which passes over.a drive pulley 20, a pair of idler pulleys 22 and 24', respectively,and a form block 26. The drive pulley is mount.- ed upon the upper endof the vertically disposed shaft of a motor 28 carried by a bracket 30which is supported by the standard 10 below the frame 12, and the upperend of this shaft extends within the frame 12. The drive of the motor 28is controlled by a switch-29 positioned upon the forward end of theframe 12 and connected by a conduit 31 to a control box 33 mounted uponthe standard 10, the control box 33 being connected to the motor 28 by aconduit 35. Beneath the motor 28 and also supported by the bracket 30 isa casing '32 having an exhaust blower. A rotary blower member within thecasing 32 is driven by the lower end of the shaft of the motor 28. Thesuction created by the blower is com- 105 mun-icated to the interior ofthe housing 12 by a conduit 34 leading from the housing 12 to the inletside of the blower casing 32. The dust which arises from the abradingaction of the belt 18 upon the work will be conveyed by the draft 110passing through the housing 12 and discharged through the exhaust end ofthe casing 32 into a dust-collecting conduit.

The idler pulley 22 (Fig. 2) is journaled in a bracket 36 which ismounted in the housing 12. The idler pulley 24 is journaled in a bracket38 which is in the form of a bell crank pivotally mounted in the housing12 upon a fulcrum pin 46. An arm 42 of the bracket 38 carries a shortupstanding pin 44 which enters a groove 46 in a horizontally disposedscrew 48 which is threaded in a boss formed in the side wall of thehousing 12. The adjusting screw 48 is operated by a hand-wheel 50through a clutch 52 comprising a pair of members having interengagingteeth which are so inclined as to slip when excessive resistance to theadjusting screw 48 is encountered. A spring 54 maintains the clutchmembers 52 yieldingly in operative engagement. The turning of theadjusting screw 48 to move the arm 42 towards the right, as viewed inFig. 2, serves to move the pulley 24 to the left, thereby increasing thetension in the belt 18. The extent, however, to which the belt 18 maythus be tensioned is limited by the slipping of the clutch 52.

The form block 26 (Fig. 3) is carried by a bracket 56 which has anupstanding portion which is slidable in a vertical guideway formed in anupstanding portion 58 of the frame 12. A vertically disposed adjustingscrew 60 is threaded into the upper end of the upstanding portion of thebracket 56 and has formed upon it a flange 62 which enters a slot 64formed in the upstanding portion 58 of the frame. The vertical positionof the screw 60 is determined by the engagement of the flange 62 withthe slot 64 so that rotation of the screw 60 will effect an upward ordownward adjustment of the bracket 56. The bracket 56 is clamped in itsadjusted position by means of clamping screws 65 passing throughvertically disposed slots 67 (Fig. 4) formed in the upwardly extendingportion of the bracket 56 and threaded into the upwardly extendingportion 58 of the frame 12. The form block 26 is slidably mountedbetween and supported by a pair of flanges 66 extending downwardly froma horizontal portion of the bracket 56, and an end plate 68 is securedto the rear ends of the flanges 66 by a pair of screws '70 and serves asa rearward stop for the form block 26. A binding screw 72 threaded intothe horizontally extending portion of the bracket 56 engages the uppersurface of the form block 26 and screws it firmly in position withrespect to the bracket 56. The

form block 26 has a vertically disposed operative face '74 which isshaped to a curvature complemental to that of the desired contour of thebreast surface of the heel to be scoured, and it provides a backing forthe scouring belt 18 and to the securing belt 18. In order, however, to

insure that any heat generated by such friction will be rapidlydissipated, the form block 26 is the illustrated machine is composed ofmetal and is provided with a plurality of heat-radiating fins 80. Inorder to insure a contacting surface for the binding screw 72, a bridgemember 82 extends crosswise of the fins 80.

A gage member 84 is provided for determining the position of a heel withreference to the plane of the tread surface of the heel relatively tothe operative surface of the abrading belt 18 as it passes over the formblock 26. The gage member 84 has a pair of operative surfaces 86 (Fig.4) for engaging portions of a heel-breast surface of each side,respectively, of a heel, the surfaces 86 tapering as they approach thecentral portion of the heel-breast surface and each being formed to acurvature substantially complemental to the heel-breast surface which itis to engage. The gage member 84 has a central portion 88 which bridgesthe two operative portions and which is offset to avoid contact with thecentral portion of the heel-breast surface. An advantage of the taperedconstruction above described resides in the fact that in most instancesthe shank of the shoe intended to be operated upon is arched, and thework-engaging surfaces 86 may engage those portions of a heel-breastsurface adjacent to the shank of a shoe and included between the surfaceof the shank and a plane which is tangent to the shank at its centralportion. The gage member 84 thus leaves exposed for scouring action allthat portion of the heel-breast surface which lies between the plane oftangency of the central portion of the shank and the tread surface ofthe heel. The gage member 84 is rigidly secured by screws 90 to theends, respectively, of a pair of downwardly extending arms 92 of a yokemember 94 which is pivotally mounted upon fulcrum pins 96 mounted incars 98 (Fig. 4) formed upon a cross-piece 100 (Fig. 3) which is rigidlysecured by means of screws 102 upon the forward end of the bracket 56.Formed upon the cross-bar 100 is a rearwardly extending lug 104 whichextends over the yoke member 94. Threaded into the lug 104 is avertically disposed adjusting screw 106 which engages the upper surfaceof the yoke member 94 and thus limits the extent of rearward movement ofthe gage member 84, thereby determining the depth of the scouringaction. Formed in the lug 104 is a boss 108 (Fig. 4) having acylindrical bore in which is mounted a compression spring 110 whichbears upon the upper surface of the yoke 94 and urges the gage 84outwardly and away from the operative surface 74 of the form block. Anadjusting screw 112 is threaded into the upper end of the boss 108 andacts through a disk or plunger to regulate the compression of the spring110. Threaded into the yoke 94 is a vertically disposed adjusting screw114 which bears against the upper surface of the forwardly extendingportion of the bracket 56 and limits the outer movement of the gagemember 84.

Rigidly secured upon the upper surface of the yoke 94 by means of screws116 is a cross member 118 which carries a vertically disposed guideway120. Mounted in the guideway 126 is a slide 122. A vertically disposedadjusting screw 124 is threaded through a lug 125 formed upon the upperend of the slide 122 and bears against the upper end of the guideway120. The rotation of the adjusting screw 124 determines the position ofvertical adjustment of the slide 122, and the slide 122 is then clampedin adjusted position by means of a binding screw 126 which is threadedthrough the slide 122 and bears against the guideway 120. Pivotallymounted upon a fulcrum pin 128 which is threaded in the slide 122 is agage member 130 which has formed upon its lowerend across-bar 132 havingits under surface formed to aconvex curvature. The fulcrum pin 128 isprovided with a knurled head 134 rotation of which serves to advance thethreaded portion of the pin 128 intothe slide 122 and thus to bind orclamp the gage member 130 in its operative position. An upwardlyextending portion 136 of the gage member 130 chgages a lug 138 formedupon the slide 122 to determine the operative position of the gage 130.

When it is desired to remove or replace the form block 26, it is onlynecessary to turn the knurled head 134 sufiiciently to loosen the gagemember 130 whereupon the latter may be swung upwardly out of the way.

A gage member comprising a plate 140 (Fig. 3) is mounted for universalmovement by means of a ball-and-socket joint 142 upon the end of adownwardly extending adjusting screw 144 which is threaded through aboss 146 formed upon the upwardly extending portion 58 of the frame 12.A longitudinal slit 148 is formed in the boss 146, and a clamping screw150 serves to tighten the boss 146 about the adjusting screw 144. Aknurled head 152 is provided for turning the adjusting screw 144 toinsure upward or downward movement of the gage member 140.

In the operation of the machine, a shoe S having a heel base H, as shownin Figs. 3 and 4, is presented to the gage member 34 which serves tohold the heel breast of the shoe S out of contact with the abrading belt18 until the correct position of the heel breast, i. e., a face-to-facerelation with respect to the operative portion of the scouring belt, hasbeen established. The operative sur faces 86 of the gage memberdetermine the angular position of the heel in substantially the plane ofthe tread surface of the heel, that is, a plane which extends lengthwiseand widthwise of the heel. The gage member 84 thus orientates the heelin relation to the scouring tool. The gage member 132 serves todetermine the heightwise position of the heel I-I, while the gage member140, which engages the tread surface of the forward portion of the shoeS, acts in conjunction with the gage member 84 to determine the verticaland lengthwise inclination of the heel-breast surface with respect tothe operative position of the abrading belt 18. In the operationillustrated in Figs. 3 and 4, substantially the entire heel breastexcepting those portions engaged by the operative surface of the gage 84is to be secured. The gage member 132 is, therefore, adjusted upwardly adistance suiiicient to permit the heel H to extend upwardly until thelower edge of the securing belt 18 is almost tangent to but out ofcontact with the shank portion of the shoe S. Such adjustment of thegage member 132 prevents marring of the shank by the lower edge of thescouring belt. In many instances, however, and particularly in the caseof a heel provided with a rubber or composition top lift T, it is notnecessary to scour a considerable portion of the heel breast but onlythe breast surface of the top lift T, and in such cases the gage 130 maybe adjusted downwardly to insure that only the breast surface of the toplift T will overlap and come into engagement with the abrading belt 18.Assuming now the shoe S to have been presented to the gages 84, 132 and140, the operator presses upon the shoe, causing the gage 84 to yieldrearwardly and bringing all portions of the surface to be scouredsimultaneously into engagement with the scouring belt 18. The yieldingof the gage member 84 allows the scouring action to proceed until thescrew 196 prevents further yielding. The scouring action is thencomplete, and any further pressure upon theheel will be resisted by thegage member 84, which thus determines the position of the heellengthwise of the heel with respect to the scouring belt. Aspreviously'stated, the adjustment of the screw 106 determines the depthto which the heel breast can be scoured. In the case of heels providedwith top lifts, the unfinished breast surface to the top lift usuallyextends slight beyond the breast surface of the heel base, and, when itis clesiredto finish the breast surface of the top lift only, the screw106 may be so adjusted as to cause the finished breast surface of thetop lift to be continuous with thebreastsurfaceoftheheelbase. It will benoted that, as the gage 84yields rearward ly from inoperative position,the gage member 130 moves with it so that there will be no relativemovement between the tread surface of the top lift T and the cross-bar132. An advantage in avoiding such relative movement resides in the factthat many top lifts are provided with irregu lar non-slipping treadsurfaces, and, if such relative movement were permitted to occur, itmight vary the relative vertical relation between the tread surface ofthe top lift T and the cross-bar 132. The convex under surface of thecross-bar 132 enables it to accommodate any angular position of thetread surface of the top lift T which may be imposed upon the shoe bythe gage 146. It also serves to effect substantially line contact withthe tread surface of the top lift T and thus avoids unnecessary contactwith surface irregularities of the character above referred to. It willbe noted that the gage 130 not only determine the heightwise position ofthe heel H but also prevents accidental transverse inclination of theshoe. other words, it serves to determine the position of the heel in aplane which is heightwise and trans verse of the shoe S. The gage 140 inconjunction with the gage member 130 serves to determine the angularposition of the shoe in a plane which is vertical and longitudinal withrespect to the shoe.

The machine, in the form above described, may also be used for thescouring of heels prior to their attachment to shoes. For work of thischaracter, however, it may be more convenient to adopt the modificationshown in Fig. 5, wherein the guideway 120 is removed and a guideway 220is substituted therefor. A slide 222 is vertically movable in theguideway 220 and may be clamped in any desired position of verticaladjustment with respect thereto by means of a binding screw 224 which isthreaded into a forwardly extending lug 226 of the slide 222 and whichbears against the guideway 220. J ournaled upon a pin 228 which iscarried by the upper portion of the slide 222 is a downwardly extendingyoke member 236 having a pair of outwardly extending yoke arms 232 whichcarry trunnion pins 234 upon which is journaled a plate or work table236. A gage 238 which may be calibrated in degrees is secured upon oneof the arms 232 and enables the operator to adjust the plate 236 toobtain the desired angular relation between the heel-breast surface andthe scouring belt. The trunnion pins 234 have their ends threaded intobosses 240 formed in the plate 236 and serve upon rotation to clamp theplate 236 in adjusted position. To prevent any swinging movement of theyoke member 94 about its trunnion pins 96, the screw 112 may beloosened,or

the screw 112 and the spring may be removed, and

the adjusting screws 116 and 114 tightened to clamp the yoke member 94in such a position that the edge of the plate 236 just clears theabrading belt 18. A gage 242 which is mounted upon the operativeposition of the work plate 236 facilitates the centering of the heel Hand serves to hold the heel H against the sidewise drag of the scouringbelt 18. When employing the work plate 236 for the securing ofunattached heels, it is more convenient, as shown in Fig. 5, to rest thetread surface of the heel upon the work plate 236. When it is desired toremove and replace the form block 26, the yoke 230 may be swung upwardlyby the plate 236. It may be secured in its operative position by abinding screw 244 which is threaded through a boss 2&6 formed in oneside of the yoke member 230, the end of the binding screw bearingagainst the side of the lug 226.

It is evident from the foregoing description that the illustratedmachine is not limited to operations upon complete heels but may beemployed upon heel bases to which top lifts have not yet been applied,and also upon top lifts alone. The modified form of the machine shown inFig. 5 can very conveniently be employed to scour top lifts alone. Inthe following claims, therefore, as well as elsewhere in thespecification, the term heel is employed, for convenience, to denote notonly a complete heel but a heel base or a top lift as well, and it isunderstood that the term heel is to be taken in this generic senseexcept where a more restricted meaning is necessarily implied by thecontext.
